GOT an ACTION and BARREL NOW WHAT?

[ICANHITHIMMAN]

I have a Howa LA and a 28" 30 cal 1-10 twist barrel what should I build the 300win mag or a 300 ultra.

Intended use will be whitetailed deer, black bear, hogs, elk, moose etc etc. I want to be leathal at at least 1000 yds.

How much will I gain by chosing the RUM over the Win MAG?

Is a 28" barrel enough for the RUM it will finish shorter maybe 27" if I am lucky.

Well...

What contour is your barrel?

How heavy is your rifle going to be?

Have you shot either round?

I hate it when people answer my questions with a question, but in this case it might help you decide on which cartrisdge to choose.

Some guys are going to say "RUM all the way". But, if you're building a light carry rifle the RUM can cause flinching nightmares - it can be a handful without a brake on it and some of us don't like brakes on their hunting rigs for obvious reasons.
If your barrel profile is heavy and you're used to big rounds, then this flat shooting SOB may be for you.

The WM is no slouch. It will easily get you to 1000 yrds and knock down whatever you hit. The WM with a 200 gr Accubond is a lethal combination. In a light rifle, the WM is tolerable.
Billy Bob is going to say he shoots a box of shells through his RUM and doesn't feel a thing - good for him, I'm more accurate when I don't think about being punched in the shoulder by my rifle.
If you reload then this might be the one. Once you fire-form your brass the head spacing issue off of the belt is a non issue (a custom chamber make it mute anyway).

So, decide if it's going to he a carry gun or more of a heavier hunting long range shooter and shoot both cartridges before you decide.

I wouldn't eliminate the WSM either. It's a legit 1000yd 30 cal and on a long action you won't have to worry about seating depth being a problem and you lose the belt. If you go the RUM route a longer mag box is a real good idea. I shoot and love the RUM but it's on a #1 with a muzzle brake. I guess I did the opposite of your request... now you have more too choose from.

I have a LA and I dont want to waste it on a round that will fit in a SA The barrel is .730 at the muzzle it will have a break its not a traditional carry rig but I will be carrying it. I hope it to weigh in at around 12lbs.

ICHHM, i'd go with the RUM.....Billy Bob

 

[ICANHITHIMMAN]

Do you guys think the 28" blank I have is enough for a Rum seams like I am short changing the round a little in the veloicty dept??????

 

[davewilson]

if you can't "get r done" with a 28, a longer barrel won't help.

For selection of factory ammo, the WM wins, for LR, the RUM wins.
